Buying Guide – How to Choose the Best Blank Rewritable Rfid Cards

Selecting the right blank rewritable RFID card depends on several technical and practical factors.

Frequency Compatibility

RFID cards operate at either 125kHz or 13.56MHz frequencies which are not interchangeable. You must match the card frequency to your existing readers or locks to ensure they function correctly.

Always check your system specifications before buying to avoid purchasing incompatible cards.

Chip Type

Common chips include T5577 for low frequency and MIFARE Classic or NTAG for high frequency. T5577 is versatile for duplication while MIFARE offers more security sectors for professional use.

Choose a chip type that supports the specific protocols your system requires.

Rewrite Capability

Some cards allow rewriting of the UID while others have a fixed locked UID for security. Rewritable cards are better for testing and changing credentials whereas fixed UID cards are safer for permanent access.

Decide whether you need flexibility or higher security for your use case.

Pack Size

Cards are sold in packs ranging from 5 to 100 pieces. Buying in bulk usually lowers the cost per card which is beneficial for larger deployments.

Assess your current needs and future growth to determine the appropriate pack size.

Durability and Material

Most cards are made of PVC which is durable and waterproof. Some options feature thicker materials for industrial use or special surfaces for printing branding.

Select material that can withstand the environment where the cards will be used.

Printer Compatibility

If you need branded cards check if the surface supports thermal or UV printing. Standard inkjet printers often cannot print on PVC cards effectively.

Confirm printing requirements match the card surface to avoid wasted materials.

Security Features

Higher-end cards may include password protection or encryption keys to prevent unauthorized access. This is crucial for commercial environments needing robust security protocols.

Opt for cards with security features if protecting sensitive access is a priority.

Writer Requirements

Blank cards must be written to a compatible writer before use. Ensure you have the necessary hardware and software to program the cards you buy.

Check writer support for the specific card chip to avoid compatibility hurdles.

How to Use and Care for Your Blank Rewritable Rfid Cards

Before using any blank card connect it to a compatible RFID writer and program the desired data or ID number. The card will not work until it has been successfully written with credentials.

After programming test the card with your reader or lock to verify it functions correctly. Keep the written data backed up in case you need to reset or change credentials later.

Store cards in a cool dry place away from magnetic fields or extreme heat to maintain durability. Avoid scratching the chip area or bending the card excessively to ensure long-term reliability.
